Hi all, long time member, very infrequent poster ..
Have a 992 Carrera S .. love it. As has been written many times, it's very subtle in the noise department, despite having a so-called sports exhaust in the form of PSE. In reality, you might get a bit more burble at idle but in all likelihood most of the extra noise is because they also open the sound symposers too.
I know there are aftermarket exhausts costing £thousands. And I know you can buy a box with some remote controls which open the flaps and give you more noise. If you're in the UK I priced this up at £700. I know you can also get a tune which will do the same thing but #warranty ...
It's the flaps in the exhaust .. they just need to stay open! I know you can't just disconnect the wires (cue Christmas on your dashboard) but if you could buy something you just plugged in for less than £100 that opened the flaps permanently, who'd buy it? I think I would! Let me know and I'll see what I can do ..

So it's an electronic one? No tube connecting to the flap mechanism? Are you 100% sure? The Capristo upgrade for a 992 is run off a vacuum (from a quick Google).
I think I have a solution for 'permanently open'. Easy to fit - can do it without jacking the car up or removing engine cover - no dashboard lights, no issues so far.
Certainly louder on cold start - more crackles in all drive modes - more 'fruity'. But I wouldn't say it is any noisier than cars I've had previously - M3/M5 spring to mind. Not particularly loud at speed - almost feels like how Porsche might have designed it to sound with PSE before the regulatory department got involved ..
We're off on a little European jaunt next week and I plan to leave this in place to see how it behaves. Have an idea how it could be made switchable too, and even variable .. but that'll have to wait till I'm back :-D

Well i'm definitely no youtuber (thank goodness) but I coerced my son to take some videos and I stitched them together. Cold start, warm start, launch, drive by, etc.

Well done!https://www.youtube.com/watch?v=EMvt13C10kQ
So what did you do exactly? For me that would be just right. Not crazy loud but not quiet.

£34 sounds like a bargain for the improvement in sound. If I had a 992 I'd buy one. (I'll overlook the fact that this whole thread seems like you're setting this up as some kind of marketing exercise. 
)
Haha - you're right - it does look hugely like that!! Promise it isn't - will keep quiet now just incase it makes it worse! Was a genuine attempt at sharing what I was doing - kinda hoped that someone else had done this, actually, and could save me buying the stuff and doing all the electricals. )

From my limited understanding (which could be completely wrong of course) the electronic valves vary flap position depending on conditions like revs, throttle position and mode. The PSE will let you start with them open if the button is pressed before you start the car (but how 'open' is open...?).
I'm guessing the kit does as you say - holds the flaps open fully at all times, but would be nice to have that confirmed.
Yep - totally correct. Standard PSE operation is to open & close the flaps when you're driving around, even when the sports exhaust button is pressed. That extra noise you hear at idle when you push the button is the flap opening only a small amount. There are some videos online which show the movement of the flap at different speeds/loads. For me, that just felt like I was being cheated a bit!I'm guessing the kit does as you say - holds the flaps open fully at all times, but would be nice to have that confirmed.
